Abstract: A repeater communications module (RCM) (12) that enhances signals in a communications network comprises a processor (12-8) coupled to a communications medium and optionally to a host application ( 10).  The RCM (12) operates in one of two modes: (1) interface or host application controlled, and (2) standalone. In the interface mode, the RCM (12) receives packets from a host application (10), modifies the packets and transmits message packets in accordance with a transmit role table (TRT). In standalone mode, the RCM (12) initiates packets and transmits message packets in accordance with the TRT. All RCMs can be configured to repeat message packets which are received from the communications medium in accordance with a repeater role table (RRT). The RCM (12) includes a memory that stores the TRT and RRT. The TRT comprises a plurality of entries, and each entry comprises a destination house code, a destination device address, and a transmit repeater role identifier (TRRI). The processor (12-8) is programmed to compare a first field within a packet to the destination house codes in the TRT, and to compare a second field within the packet to the destination device addresses in the TRT, and to copy the TRRI corresponding to the TRT entry having a matching destination house code and destination device address to an RRI field in the packet, and then to transmit the packet onto the communications medium. The message packet will either be received and re-transmitted by a repeater (12) or received directly by the destination device (14).

Title: Multilayer porous fabric
Inventor: BAKER SAMUEL M
IPC: B32B5/02
Filed: 1999-03-16
Granted: 2007-08-21
Abstract: A multilayer porous fabric comprises a porous core fabric provided with a plurality of suitably located hook means structures on at least one of its surfaces. At least one layer of nonwoven fibrous batt, pre-needled to a desired density, is attached by entanglement onto the hook means by pressing the core fabric and batt together, so that the hook structures engage with and entangle sufficient fibers from the batt to anchor the batt reliably to the core fabric without further needling. The multilayer fabric is then ready for use without further processing and can be handled before use, for example in preparation for installation in a papermaking machine press section. The porous core fabric may be formed by weaving or as an extruded sheet. Compressive loads applied to the porous fabric may enhance the level of entanglement of the batt onto the hook means.

Abstract: Ce dispositif et le procédé afférent d'enroulement de bandes de papier ménager (15) sur une bobine mère (25) permettent d'obtenir un poids à la rame plus uniforme, un meilleur allongement dans le sens de fabrication ainsi qu'une meilleure épaisseur moyenne de feuille en liasse si l'on se réfère aux caractéristiques correspondantes de feuille en des points représentatifs sur toute la bobine. Dans le cadre de ce procédé et au moyen du dispositif de l'invention, la bande de papier ménager (15) est appliquée sur un mandrin de bobine mère (26) et ce, à l'aide d'un organe souple (18), une courroie de transfert par exemple franchissant un espace dépourvu de soutien entre deux cylindres-support (21, 22). La bande passe de la courroie de transfert (18) à la bobine mère (25), celle-ci venant appuyer sur la feuille et/ou la courroie de transfert en un point donné de l'espace dépourvu de soutien. Le déport résultant de la courroie de transfert (18) est détecté et, en réaction, la position du mandrin est modifiée de manière à agir sur ce déport et à l'amener au niveau souhaité. Il est, de ce fait, possible d'appliquer à la bobine une légère pression linéaire prédéterminée au point de pinçage lorsque la bande de papier ménager (15) s'enroule sur la bobine de même qu'il est possible de produire de grosses bobines mères de papier ménager à forte épaisseur moyenne de feuille en liasse, ce papier étant doté des caractéristiques souhaitées une fois déroulé.

Title: Joint multiple program error concealment for digital audio broadcasting and other applications
Inventor: SINHA DEEPEN
IPC: H04H20/00
Filed: 2000-01-14
Granted: 2004-08-17
Abstract: The invention provides methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system.  In an illustrative embodiment, a multiple program coder encodes a bitstream associated each of the programs, in accordance with a specified bit allocation. An outer code encoder receives the encoded bitstreams from the multiple program coder, and jointly applies an outer code, e.g., a CRC code, RS code, BCH code or other type of linear block code, to subblocks of a subset of the resulting encoded bitstreams. The outer code is applied such that subblocks of each of the encoded bitstreams in the subset of the encoded bitstreams are associated with a single outer code block. The number of subblocks associated with a given outer code block may be an integer or non-integer number of code blocks. The invention allows a designated number of program subblocks to share a given outer code block, such that outer code error flags can be generated for smaller groups of bits per program than would otherwise be possible. An inner code encoder may be used to apply an inner code, e.g., a convolutional code, turbo code or trellis coded modulation, to the resulting outer code blocks.

IPC: F04B53/10
Filed: 2001-03-12
Granted: 2007-09-25
Abstract: A fluid pump dispenser of the loss motion piston type provides for maintaining the discharge open a slight interval at the commencement of each plunger upstroke while the pump chamber expands to retract product from the discharge passage into the chamber to thereby avoid the formation of product droplets at the exit end of the discharge. Such is effected in accordance with one embodiment by reducing the friction force acting between the piston and the pump cylinder relative to the friction force acting between the piston and the stem. In another embodiment an inlet valve assembly has a portion lying in the path of the piston which portion is connected by spring legs to a valve portion such that the restoring force of the spring legs shifts the piston together with the stem at the commencement of the plunger upstroke which maintains the discharge passage in open communication with the chamber.
